Specification of Letters Patent.

Application filed June 17, 1915. Serial No. 34,626.

To all whom it may concern:

Be it known that I, ARTHUR Lnn, a citizen of'the United States, residing at Herscher. in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in a Portable Power Transmission, of which the following is a description.

My invention belongs to that general class of devices for transmitting power, and relates particularly to a portable device for efliciently and conveniently transmitting power from asuitable source of energy to one or more desired machines. The invention herein described is in the nature of an improvement on that shown in my United States Letters Patent No. 1,089,485, dated March 10, 1914. The device is particularly adapted for farm use, as the source of power, as for example a gas engine, and may be transported from place to place to operate the desired machinery, such as churns, washing machines, pumps, grinders,

I shellers and similar tools or appliances.

The invention has particularly among its objects the production of an improved portable device of the kind described that is extremely simple, convenient, efficient and satisfactory, and that is applicable for practically any use to which it may be put. The present construction has the advantage of being adjustable for slight variations whereby the same may be used for driving almost any machine regardless of where the machine is located, and driving it in amost efficient manner.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Figure 1 is a side elevation of the truck and transmission elements carried thereby;

'Fig. 2 is a rear elevation of the same;

Fig. 3 is a top elevation of a portion of the same, the engine removed;

Fig. 4 is a sectional view taken substantially on line 4, 4 of Fig. 8;

' Fig. 5 is a sectional view taken substantially on line 5, 5 of Fig. 1;

Fig. 6 is a view in elevation of the aux iliary apparatusiarr'anged to coijperatewith the main transmission mechanism shown in Fig. 1;

Fig. 7 is a top plan view of the same, and

Fig. 8 is a sectional view taken substantially on line 8, 8 of Fig. 8.

Referring to the drawings, my apparatus consists preferably of a truck frame consisting of the parts 1 and 2 suitably carried by the wheels 3, or their equivalents for the purpose. Mounted on the truck frame is an upright frame, consisting of the brace and upright members 4, 5 and 6 respectively. Suitably carried by the upright frame is a shaft 7, and adjustably carried on the shaft, or in an equivalent manner, is an adjustable or swinging frame 8, which carries a shaft 9 arranged adjacent the outer end. The frame 8 is very similar to the frame shown in my patent referred to. Arranged on each side 8 of the frame is what might be termed a gear or toothed member 10, the same being secured to the arm by bolts 12, or their equivalents, passing through the spokes 11. Suitably carried by the upright 4 at each side of the machine is a gear 14, arranged to mesh with the teeth on the member 10. The gear 14 on one side is connected through the shaft 15 with the worm wheel 16, arranged to mesh with a. worm gear 17 carried by bracket 18. The worm gear 17 is arranged to be driven or controlled by a shaft 19, preferably provided with a crank end 20. As is obvious, as the crank 20 is turned in one direction or the other, the wheel 10 at each side of the machine is turned, through the shaft 15 and gears 14. At the same time, owing to the worm gear construction, the worm gear locks the gears 10, and consequently the arms 8 of the adjustable frame, against movement. This avoids the necessity of additional fastening or locking members, and the adjustable frame may be instantly changed'or varied for extremely slight adjustment in but a moments time.

,I have showna pulley 21=on shaft 7, and this through belt 22, or its equivalent, drives pulley 23 on shaft 9. Shaft 7 is driven by belt 24, or its equivalent, passing over the pulley 25, operatively connected with the gas engine 26, or its equivalent. If have shown a tight and loose pulley 27 and 28 on shaft '2', and a belt shifter 29, so that shaft 7 may be. stopped without shutting down the e e l .i

To avoid the necessity of adjusting shaft 7 and the arms 8 to loosen or tighten belt 24, I mount the engine 26 on an adjustable frame, said frame being adjustable relative to the upright frame on the truck. This frame, as is most clearly shown in Figs. 3, 4 and 8, consists of the sliding frame parts 31 and 32, projecting over the side frame parts 1 of the truck, and parts 33 and 36 arranged below the parts 1, members 34 being an ranged therebetween, as shown in the drawings. The parts are secured together by bolts 37, this forming substantially a sliding frame. The position of the sliding frame is controlled by the bolts 42, which also lock the frame in the desired position relative to the upright frame, so that the belt 24 may be maintained at the desired tension and prevent strain on the upright frame; I have shown braces 38 secured by bolts 39 to the parts 34. \Vhen the cross bar 32 is shifted and the bolts 37 extended through the desired holes 40 the braces may then be secured to the cross bars 31 and 32 by passing the bolts 39 through the bolt holes 41. These last mentioned bolt holes are also convenient for securing the engine in place. 7

It is often necessary or desirable to leave the truck outside of the building and yet drive a machine within the building, as for example, a washing machine, churn, or the like, which may be in the kitchen or in the milk house on a farm. By making the arms 8 adjustable to any point this may be very simply done. I have shown in Figs. 6 and 7 the cobperating driving element, which is connected with one of the shafts on the truck, as for example, shaft 9, as that shaft may be brought to aline with the transmitting shaft arranged within the house and coupled directly thereto. It is also possible to bring the shaft to exactly the right position above the window sill, even though the various window sills differ in height from the ground. r

Referring particularly to Figs. 6 and 7 mentioned, 46 is the shaft, which is arranged to be connected directly to shaft 9, but may be provided with a pulley 47 in addition, if so desired. Shaft 46 extends through and is carried by a bearing 48, formed with supporting brackets 49 for securing the same in place. I have shown the bearing and brackets securedto a board 50, which has hinged thereto a board 51, 52 being hinges. This construction, consisting of the two boards 50 and 51, may be inserted under the window frame or sash and the sash then brought down on the same, securely locking the device in place. This rigidly supports shaft 46. Preferably pivotally or adjustably carried by shaft 46 is an auxiliary ad ustable frame 53, which carries a shaft 54. The two shafts are connected by a belt 57 running over pulley 58 and arranged to coiiperate with the tight and loose pulleys 55 and 56. The belt shifter 59 is also shown. To support the auxiliary frame 53 I secure an adjustable leg 60 adjacent the free end of the frame. This leg is secured in place by a bolt 63. I have shown in Fig. 7 serrated plates 61 and 62, secured respectively to the frame and leg so as to give a firm grip and prevent movement of the leg around the bolt 63. The leg is also shown with a slot so the auxiliary frame may be adjusted up and down.

In driving a machine within a house or room, the truck being without, the boards 50 and 51 are placed under the window sash, frame 53 adjusted as desired, and shaft 54 suitably connected with the churn, washing machine or the like which is to be driven.

The truck is brought to the window and lower the truck, and likewise the frame 53 a may be exactly adjusted so asto bring shaft 54 to the machine to be operated. In this way excess pulleys, belts, and driving shafts are avoided, and adjustments are possible for practically every condition.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact construction, arrangement or combination of parts herein shown and described, or uses mentioned.
